What should I do if I find dropped frames during video playback?
If the video playback window is overlaid with another window, you may encounter dropped frames or find playback
performance degraded. Move the video playback window to where it will be unlikely to be overlaid with another window or
maximize the video playback window.
What should I do if I do not hear the sound from the sound output device connected to the
HDMI output port, optical output port, or headphones jack?
You need to change the sound output device if you want to hear sound from the device connected to a port, such as the HDMI
output port, optical output port, or headphones jack. For the detailed procedure, see How do I change the sound output
device? (page 148).
Why do sound interruptions and/or dropped frames occur when I play high-definition
videos, such as those recorded with the AVCHD digital video camcorder?
Playing high-definition videos requires substantial hardware resources, such as CPU, GPU, or system memory performance
on your computer. During the video playback, some operations and/or functions may become unavailable, and sound
interruptions, dropped frames, and playback failure may occur depending on the configuration of your computer.
